Upgrade from barcode to 13.56 MHz HF RFID (ISO/IEC 15693) when counter queues or stock verification take more staff time than you can spare, or book losses exceed your tolerance. Keep the barcode on every book and encode the same number on the tag, so circulation continues during conversion.
Short answer: a library with one quiet counter, stock it already verifies on time and losses within tolerance can stay on barcode. A busy college or public library with peak-hour queues, several exits or a large stock to verify should move to HF RFID, one range at a time; one that must verify every book every year (up to 20,000 volumes under GFR Rule 215) feels the shelf-audit gain first.
Identium is a BIS and WPC approved RFID manufacturer in New Delhi. We make HF and UHF tags, labels and readers, and our RFID library management system runs on HF unless a requirement points to UHF. For warehouses and retail, see RFID vs barcode in India.
| Library task | Barcode + magnetic strip | HF RFID, 13.56 MHz, ISO/IEC 15693 | UHF RFID, EPC Gen2 / ISO/IEC 18000-63 |
|---|---|---|---|
| Issue and return at the counter | One scan per item, in line of sight | A stack on the pad, read together | Many tags at once; longer range can pick up stray tags nearby |
| Self-check kiosk | Patron scans each item, one at a time | Stack on the kiosk reader; LMS link over SIP2 or NCIP | As HF, over the same SIP2 or NCIP link |
| Shelf audit / stock verification | Each book pulled or scanned one by one | Handheld wand run along the spines | Bulk reading along the shelf, UHF’s main case |
| Anti-theft gate | Barcode gives no security; separate strip and gate | EAS bit or AFI code on the tag; gate decides offline | Database look-up against a list synced from the LMS; other methods are chip-specific |
| Tag-cost direction | Lowest per item; strip bought separately | Depends on chip, label size and volume | Savings expected from UHF production volume (NISO App. C.1) |
| LMS integration | Native: the circulation screen takes a scanned barcode | Desk reader in keyboard mode enters the item ID at circulation; kiosk and gate over SIP2 or NCIP | As HF; UHF encoding in ISO/TS 28560-4 |
Sources: NISO RP-6-2012, RFID in U.S. Libraries (§§1.1–1.5, 3, App. C), the NXP ICODE SLIX2 datasheet and the Koha manual, cited below; desk-reader keyboard mode is general practice, and tag cost is directional only.
What changes at the issue counter and the self-check kiosk?
A barcode scanner needs a line of sight to each label. An HF library chip such as NXP’s ICODE SLIX2 has anti-collision, so several tags can operate in the reader field together, without line of sight (NXP SL2S2602 datasheet).
How many items a kiosk reads together depends on antenna read range and item type; CDs and DVDs reduce the stack, and untagged items and patrons with blocks may still need staff (§1.3). Kiosks talk to the library system over SIP2 or NCIP (ANSI/NISO Z39.83); see how many tags a reader can read at once.
At the desk, Koha’s BatchCheckouts system preference, with the permitted patron categories set in BatchCheckoutsValidCategories, supports batch checkout from an RFID pad that reads several item barcodes (Koha manual: Circulation).
How does an RFID gate tell an issued book from an un-issued one?
NISO RP-6-2012 (§3) names three methods:
- EAS bit. A one-bit register on the tag, cleared at issue and set again at return.
- AFI code. Citing ISO 28560-1 (the 2011 edition then current; current edition), NISO gives C2 (hex), the library-industry code, for items checked out and circulating outside the library, and 07 (hex) for checked-in items secured by AFI-based systems (§3.2.1). The exit portal interrogates for tags carrying the checked-in code (§3.2).
- Virtual deactivation. The gate looks up the tag’s unique identifier in a database (§3.4).
On HF tags (ISO/IEC 18000-3 Mode 1, the ISO/IEC 15693-based air interface NISO describes), the first two let the gate decide from the tag itself, so it keeps working when the network is down.
On UHF, security methods are chip- and vendor-specific. The database look-up is not tied to tag type (§3.4 says it “is not limited to ISO tags”): the gate checks each tag’s ID against a list synced from the LMS, which goes stale if the sync fails. ISO/TS 28560-4:2023 puts the item identifier in MB 01 and other data in MB 11.
For the tender: EAS on RFID tags is a proprietary add-on, and gates built for one silicon maker’s EAS may not secure items tagged with another maker’s chips (§3.3). Name the security method, and for UHF have the bidder state it in writing. Detection also varies with gate width, items per pass, item material and orientation (§3), so test with your own books at your own exit. For a UHF-tagged collection, our HLR200 UHF gate reader is a walk-through gate with two-way In/Out sensing.
How much does RFID change stock verification?
For central government libraries and others that follow GFR 2017, Rule 215(i) sets the verification interval by collection size (GFR 2017, updated to 31 January 2026):
- up to 20,000 volumes: every book, every year;
- 20,000 to 50,000: at least once in three years;
- above 50,000: a sample check at intervals of up to three years, with complete verification if it shows unusual shortages.
Rule 215(ii) treats a loss of five volumes per 1,000 issued or consulted in a year as reasonable, unless due to dishonesty or negligence.
With RFID, staff move a handheld wand along the spines instead of pulling or scanning each book (NISO §1.5). NISO names what makes shelf reads less reliable: thin items, metal shelf dividers, metallic ink or foil, adjacent items tagged in the same position, and CDs and DVDs.
When is barcode still the right choice for a library?
Keep barcodes, and revisit later, when:
- there is one counter and no peak-hour queue;
- the collection is small and already verified in-house within its GFR interval;
- losses are within the Rule 215(ii) tolerance;
- there is no budget or staff time for tagging labour;
- much of the stock is CDs, DVDs or items with metallic covers, ink or foil, which reduce stack reads and shelf reads;
- the library system has no SIP2 or NCIP route yet.
How do we size it by footfall, exits and collection?
Count before you buy: tags scale with the collection, but staff pads, kiosks and gates follow counters, exits and footfall.
- Counter. One staff pad per issue and return position. Count peak-hour issues and returns for two weeks; if a queue forms, add a self-check kiosk before a second pad, on the busiest footfall route.
- Exits. One gate per exit, with lanes set by clear width. A two-week peak-hour count at each exit, from a people counter on the gate or a manual tally, decides whether it needs a second lane or its own kiosk.
- Collection band. Rule 215 forces the most frequent full counts in the up-to-20,000 band (every book, every year), so that is where a handheld earns its place soonest.
- Media mix. The share of books, CDs, DVDs and items with metallic covers, ink or foil decides the tag lines you order.
What happens to our barcodes when we add RFID?
They stay. NISO RP-6-2012 (§2.5, Table 1; §2.5.2) marks the Primary Item ID as mandatory: it uniquely identifies an item, is most typically its barcode, and is used for circulation and inventory. Encode that number on the HF tag and leave the printed barcode in place.
Clean the catalogue first, so every item on the shelf has an LMS record and barcode. Then convert one range at a time at a conversion station (a PC, barcode scanner, programming software and RFID reader, which NISO says non-technical staff or volunteers can run, §1.2) while the rest circulates on barcodes. Our Koha and SIP2 integration guide covers conversion and desk-reader set-up in detail.
Which frequency suits a college library?
HF to ISO/IEC 15693 is the default. It gives stack reads, a gate that can decide offline from the tag’s EAS or AFI setting, and a mature data model in ISO 28560-2:2023 (object-identifier encoding) and ISO 28560-3:2024 (fixed-length encoding).
UHF EPC Gen2 is a legitimate choice where bulk shelf reading matters most. NISO’s 2012 report said no UHF library standard then existed (Appendix C); ISO/TS 28560-4:2023 now covers UHF encoding. EPC Gen2 and ISO/IEC 18000-63 name the same passive UHF air interface; see EPC Gen2, ISO 18000-63 and RAIN RFID.
UHF is also legal here with a reader tuned for India’s licence-exempt UHF RFID band, 865–868 MHz under G.S.R. 853(E) of 10 December 2021, used within its power and channel limits; see can I use a US 902–928 MHz reader in India.
Checks before you buy:
- A phone’s NFC reads HF library labels and can never read UHF.
- Confirm the desk reader’s datasheet lists ISO/IEC 15693, not only MIFARE, and test it with the exact label part number you will buy.
- In the tender, write “ISO/IEC 15693” without an edition year (Part 3 was last published in May 2026), and name the ISO 28560 part the encoding must follow.
- Passive library labels have no transmitter, so they need no WPC approval and no BIS registration.

How do Koha, SOUL and LIBSYS connect to RFID?
- Koha. Koha uses SIP2 between self-check machines and the Koha server, enabled on Debian installs with
sudo koha-enable-sip <instancename>(Koha manual: APIs and protocols). - SOUL 3.0. INFLIBNET’s brochure states that SOUL complies with NCIP 2.02 and SIP 2 for RFID-based surveillance and self-check-out and check-in (INFLIBNET).
- LIBSYS. LIBSYS lists SIP2/NCIP among the standards built into its library software (LIBSYS library automation). It also sells an LSmart RFID Library System for lending, security, shelf management and stock verification, supplied with RFID equipment and tags. Ask LIBSYS in writing whether a third-party kiosk or gate can use that SIP2 or NCIP interface on your version.
Pilot issue, return and gate behaviour against your live LMS version. “SIP2-compatible” is a capability to test, not a certification; Koha is community-maintained and, to our knowledge, runs no formal certification programme.
What drives the price of a library RFID system?
RFID adds book tags, gate lanes, self-check kiosks and staff stations, LMS integration and testing, conversion labour and handhelds to a barcode bill of quantities. In the GeM bids the India RFID Store read, hardware followed exits and counters rather than book count, and in the two with a published estimate, book tags were a small share of the total.
For the BOQ lines, quantities and whole-bid estimates in four GeM bids, read the India RFID Store’s library RFID system price guide; to write your own, see our RFID tender BOQ specification guide. Send us your collection size, exits and their widths, LMS and version, and media mix. We quote against specification, and custom tag orders typically turn around in 5–10 days.
